The light that is on there from the last owner is a single filament marker light that is very small. Even though the LED has 2 less lumens, it is projected in a 15 degree path so I think it will project better than an incondesent that is 2 lumens brighter but puts the light out in every direction.
I was also thinking the LED may keep the light brighter at idle with its low amp draw since I am not running a battery.
